Sähköisten kirjojen hylkäämisen syyt
2016
Sähköinen kirja ei ole yleistynyt odotetulla tavalla. Tutkimuksen tavoitteena oli selvittää, millaisia syitä potentiaaliset käyttäjät kertovat sille, etteivät käytä sähköistä kirjaa vapaa-ajan lukuharrastuksessa. Tutkimuksen aineistona oli kahdeksan haastattelua, jotka toteutettiin teemahaastatteluna. Haastateltavat valittiin sillä perusteella, että he eivät olleet käyttäneet sähköistä kirjaa tai olivat keskeyttäneet niiden käytön. Aineistoa analysoitiin teemoittelun ja laskemisen avulla. Lisäksi tarkasteltiin, missä vaiheessa innovaation omaksumisprosessia sähköinen kirja hylättiin ja mitkä tekijät voisivat vaikuttaa niiden myöhempään omaksumiseen. Tutkimuksen mukaan yleisin sähköisen kirj…
Implementing structured document production to support enterprise content management
2017
Within enterprise content management (ECM), the major goal is to develop and deploy systematic solutions for managing documents and other content items. ECM implementation concerns the development and deployment of new content management solutions and practices in an organization. Extensible Markup Language (XML) offers a standardized format for documents supporting the management and preservation of documents as structured documents. However, the deployment of XML may require a demanding standardization process, changes in work practices, and new tools for document management. Consequently, this research explores the implementation of structured document production environments. The focus …
An Efficient Network Log Anomaly Detection System Using Random Projection Dimensionality Reduction
2014
Network traffic is increasing all the time and network services are becoming more complex and vulnerable. To protect these networks, intrusion detection systems are used. Signature-based intrusion detection cannot find previously unknown attacks, which is why anomaly detection is needed. However, many new systems are slow and complicated. We propose a log anomaly detection framework which aims to facilitate quick anomaly detection and also provide visualizations of the network traffic structure. The system preprocesses network logs into a numerical data matrix, reduces the dimensionality of this matrix using random projection and uses Mahalanobis distance to find outliers and calculate an a…
Cultural Politics of Love and Provision among Poor Youth in Urban Tanzania
2015
This article examines how urban youth in the poorest neighbourhoods of Dar es Salaam negotiate the terms of transactional intimacy, that is, heterosexual relations in which men are expected to provide for women materially. Using the concept of ‘affect’, I argue that this negotiation involves different levels of male providership, as well as moral values attached to notions of ‘true love’ and the Swahili concept of tamaa. Poor men and women view their agency differently within transactional intimacy, with women describing themselves as exploited by men who do not fulfil their end of the transactional bargain, and poor men portraying themselves as deeply disempowered in comparison to wealthie…
Memorializing mass deaths at the border: two cases from Canberra (Australia) and Lampedusa (Italy)
2017
In this paper, we compare two seemingly very similar instances in which individuals and organizations within the borders of the global North have memorialized the deaths of irregular migrants at sea: the SIEV X memorial in Australia’s national capital Canberra, and the Giardino della memoria (Garden of Remembrance) on the Italian island of Lampedusa. Unlike ephemeral manifestations of grief, potentially these memorials have effects that reach well beyond their creation. We relate the differences between the memorials to the contexts within which they were created: an immediate local response involving people directly affected by the disaster’s aftermath, on the one hand, and a delayed natio…
Witnessing the experience of European bordering: Watching the documentaryUnder den samme himmelin an immigration detention centre
2017
This article draws on theories of bordering and mediated witnessing to examine a documentary film that mediates migrants’ experiences of bordering in Europe. My analysis of Under den samme himmel/Days of Hope shows how the film captures the multiplicity of bordering practices, from geographical to socio-cultural borderings. The analysis is informed by watching and discussing the film in an immigrant detention facility in Finland with people who experienced and eye-witnessed experiences similar to those depicted in the film. This creates a sense of co-presence of the experiential landscapes in the border zones, and the film invites viewers to consider borders not as lines in the landscape, b…
Of Walls and Fences: Brexit and the History of Cross-Border Migration
2019
Champions of Brexit have employed a large arsenal of arguments to boost their case for a Britain better off on its own, freed from its current European entanglements. All kinds of supposed ills have been linked to the country’s EU membership in British public debates over the years, ranging from petty bureaucratic absurdities, such as directives regarding crooked bananas, to heavy-handed rulings on higher matters of domestic and foreign policy. Lamentations about continental meddling have been accompanied by grand, nostalgic visions of an unfettered future Great Britain, ready to return to its proper, independent role on the global stage once it manages to cast off the shackles imposed by B…
Growth Into Citizenship: Framework for Conceptualizing Learning in NGO Interventions in Sub-Saharan Africa
2018
This article develops a theoretical framework for analyzing adult learning in projects aiming to strengthen citizenship implemented by nongovernmental organizations, especially in the contexts of sub-Saharan Africa. On the basis of a review of international development research, we suggest that a new framework should address the need for a conceptualization of learning as a gradual process and for capturing the gap between ideal models and everyday experiences of citizenship. We argue, building on John Dewey’s philosophy, for a framework of growth into citizenship, and introduce the notions of learning as reorganization of habits and the method of democracy as an avenue for learning as nove…
Visibility without voice: Media witnessing irregular migrants in BBC online news journalism
2016
In the analysis of journalistic representation of irregular migration to Europe, rather little attention is given to the variation of modes and genres of journalism. Most studies focus on text in ‘old media’ and the news genre. This article analyses affordances of different modalities and genres of online journalism in framing irregular migrants. Media framing in BBC online news coverage of a mediatised conflict in Spain, defined as a ‘migration crisis’, is analysed with multimodal social semiotics. While mediation makes global audiences witness tragedies at Europe's borders and online journalism affords more voice and deliberation for migrant sources, the frames of threat and victim domina…
Unitarinat : lasten unien jakamisen ja kertomisen muodot
2016
Tämä pro gradu –tutkielma käsittelee esiopetusikäisten lasten ryhmässä toteutetun taideprojektin aikana esiin nousseita tarinoita unista. Työ pyrkii löytämään vastauksia lasten kerronnan tapoihin ja muotoihin. Työssä keskeiseksi nousee tutkimusta varten kehitetty käsite unitarina. Unitarina on luova- ja kollektiivi-nen prosessi, jonka kautta lapset kertovat tarinoita näkemistään unista monin eri menetelmin. Tutkimus lähestyy kysymyksiä unitarinan synnystä, sen olemuksesta ja tavoista joilla unet tarinallistuvat ja sanallis-tuvat lasten puheessa ja piirustuksissa. Tutkimus on luonteeltaan laadullinen tutkimus. Siihen osallistui yhteensä 14 lasta. Aineiston keruu to-teutettiin eräässä kaksiki…
